:00:24. > :00:34.One Show with Alex Jones. And Matt Baker. Hang on a minute. We are on
:00:34. > :00:45.
:00:45. > :00:50.air half an hour early. Lovely Dave. Brewer Dave. No swearing. We are on
:00:50. > :00:55.a bank holiday and I am glad you can join us. Let's find out how our
:00:55. > :01:04.guest would have dealt with noisy grammars. Is Caroline Quentin.
:01:04. > :01:09.Hello, everybody. Lovely to see you. Have you heard about this drumming?
:01:09. > :01:14.Yes, I heard it on the news when I woke up this morning. This is the
:01:14. > :01:21.moment a furious Helen Mirren silenced streets drummers after the
:01:21. > :01:25.first act of her play. She is there with the wig and the cardigan as the
:01:25. > :01:32.Queen and giving the conductor some hassle. She did not use polite
:01:32. > :01:36.language. In fairness to Dame Helen Mirren, when you come offstage you
:01:36. > :01:41.tend to be full of adrenaline and she was probably getting angrier on
:01:41. > :01:45.behalf of the audience throughout the entire show and I understand it.
:01:45. > :01:52.I have had that feeling on stage myself when there is constant noise
:01:52. > :01:59.going on. I remember once in the west end at the end of the show the
:01:59. > :02:09.ghosts have to walk forward and you have to sing without any music. You
:02:09. > :02:09.
:02:09. > :02:14.take your note from one tiny note played. I wanted you to carry on. I
:02:14. > :02:21.thought you would never ask, but behind the theatre is a fire
:02:21. > :02:31.station. Suddenly the fire engine went. All the ghosts went forward
:02:31. > :02:31.
:02:31. > :02:35.screaming, do you hear the people saying? Your voice is brilliant.
:02:35. > :02:40.Another time my dog ran onstage during the show. I had him in the
:02:40. > :02:48.dressing room and he ran on. I freaked out completely. I was
:02:48. > :02:53.hopeless. I yanked him off. These things happen. We are sure Helen
:02:53. > :02:58.Mirren is not the only one to lose her rag this bank holiday weekend,
:02:58. > :03:04.so if you were passed breaking point, we would like to hear about
:03:04. > :03:10.it. If you would like to apologise, why don't we do it on behalf of you.
:03:10. > :03:17.If you have got a photo, all the better. We may have our own apology
:03:17. > :03:22.to make. Today at Kempton Park Mascot Grand National took place.
:03:22. > :03:29.There is our entry, Onsie, the squirrel. He may have been a bit too
:03:29. > :03:33.competitive. He threw his not away. We will find out how he gets on a
:03:33. > :03:39.little bit later on. This weekend, many lifeguards were back on duty
:03:39. > :03:44.for the first time this year. speedboat accident in Cornwall is a
:03:44. > :03:49.reminder about what can go on in the water and it is a good time to
:03:49. > :03:59.salute the men and women who keep us safe at the seaside. They have got
:03:59. > :04:01.
:04:01. > :04:05.plenty of stories to tell. It is not like Baywatch. Some days it is a
:04:05. > :04:12.roaring gale coming in, there is nobody on the beach, but we have
:04:12. > :04:17.still got to be here just in case. Growing up in Cornwall there is not
:04:17. > :04:24.much to do apart from having fun in the beach or the sea. I am pretty
:04:24. > :04:27.much a beach bum and lived on the beach. All your friends are working
:04:27. > :04:35.9-to-5 and they are itching to get on the beach and you are living the
:04:35. > :04:42.dream. We have got to concentrate and be on the ball from the minute
:04:42. > :04:47.we start work at ten o'clock until the minute we finish at six. Being a
:04:47. > :04:51.bank holiday weekend we are going to be busy. This is when the lifeguards
:04:51. > :05:01.get onto the beach and the season has started. We are always
:05:01. > :05:04.
:05:04. > :05:10.monitoring the sea. We can keep an eye on the bigger picture. I tend to
:05:10. > :05:16.use a paddle boards to rescue people. The adrenaline kicks in and
:05:16. > :05:26.all the training takes over. We do have too literally run straight in
:05:26. > :05:28.
:05:28. > :05:35.wearing Speedo's, but that is not that often. There are a couple out
:05:35. > :05:42.there, please keep an eye on them. I am a schoolteacher, I have never had
:05:42. > :05:47.to rescue one of the schoolkids. So, come out and rescue me. I do not
:05:47. > :05:53.know how that would go down. A lot of people who get rescued are
:05:53. > :05:57.embarrassed. Some of the guys are shouting and screaming and you get
:05:57. > :06:02.to them and they say, thanks. They get to the side and their families
:06:02. > :06:09.are embarrassed, I cannot believe you did that. They are crying
:06:09. > :06:13.almost. You need to come into the sure and go between the red and the
:06:13. > :06:16.yellow flags. You get people doing stupid things which is annoying
:06:16. > :06:21.because if they listened to you in the first place, they would not be
:06:21. > :06:28.in that situation. My biggest fear is potentially dealing with children
:06:28. > :06:33.and babies. Having never dealt with a young child, perhaps that is why
:06:33. > :06:37.for me it is something I am particularly worried about.
:06:37. > :06:43.fiance hates me being on the beach all day because I cannot switch off
:06:43. > :06:52.completely when we sit in the sand. She says I started looking at the
:06:52. > :06:58.water and scanning it and saying is everybody OK. And a chief lifeguard,
:06:58. > :07:02.Philip Goodeve-Docker, it is here with us today. A fantastic name. The
:07:02. > :07:08.speedboat interdict yesterday was on your patch. It was, I covered the
:07:08. > :07:13.south-west. It was a tragic incident. All of our thoughts are
:07:13. > :07:19.with the family for their terrible loss at this time. And what a great
:07:19. > :07:24.job the emergency services did, but tragic nonetheless. Putting that
:07:24. > :07:29.instance to the side, how many of your lifeguards have been into the
:07:29. > :07:37.water this weekend? We have had 34 beaches covered, so it is a gradual
:07:37. > :07:45.start. We will have 234 by the end of the season. We have had three
:07:45. > :07:52.good rescues, two at constant time. You know it well, Caroline. I love
:07:52. > :07:59.it, it is a fabulous beach. surfers were rescued on Saturday and
:07:59. > :08:05.another yesterday. And a young child on an inflatable at Weymouth.
:08:05. > :08:10.of your work is about prevention. is, mostly, trying to stop people
:08:10. > :08:13.from getting into difficulty and into the wrong place. That is the
:08:13. > :08:23.bulk of our work, but when things go wrong, we are there to pull them
:08:23. > :08:23.
:08:23. > :08:29.out. This is how people know when it is safe to go into the water.
:08:29. > :08:33.most important either red flag and the yellow flag. If you see those,
:08:33. > :08:43.stay in between the red and the yellow flags. The red flag indicates
:08:43. > :08:43.
:08:43. > :08:47.danger. The black and white flag is for surf craft area. The orange one
:08:47. > :08:53.indicates the wind strength. That would have been flying at Weymouth
:08:53. > :08:59.yesterday. Is it right your husband was a lifeguard. No, I would love it
:08:59. > :09:04.to be, but he was a lifesaver at a swimming pool in Leicester. He did
:09:04. > :09:14.save someone's life. He saved a little boy's life, but he spent most
:09:14. > :09:20.of his time going like this. Preventative measures. But he was
:09:20. > :09:24.never wearing Speedo is on a sandy beach. It was a shame. Now, for
:09:24. > :09:30.those who think we are already living in a Big Brother society, it
:09:30. > :09:36.is time for you to look away now. Anita Rani has been test driving a
:09:36. > :09:41.new camera that records all your moves on the road. It has already
:09:41. > :09:46.caught some shocking footage. Nowadays there are cameras watching
:09:46. > :09:51.as pretty much everywhere and it is no different on our roads, but our
:09:51. > :09:54.driving could soon be under closer scrutiny thanks to this advice. It
:09:54. > :10:00.is basically a camera that records everything that is happening out
:10:00. > :10:06.there constantly on loop. It is very clever and it knows the speed I am
:10:06. > :10:12.going out and the location I am in and even my GeForce. If I were to
:10:12. > :10:18.witness an accident, the information recorded on that could prove vital.
:10:18. > :10:22.One costs around �100. This man has had one in his car for the past
:10:22. > :10:27.three years. Some people might think it is strange you decided to have a
:10:27. > :10:33.camera on your car to follow and snoop on other people's driving.
:10:33. > :10:36.This is not to do that, it is the fact I can protect my own licence.
:10:36. > :10:43.Should anything ever happen, at least I can present my side and say
:10:43. > :10:48.it was not me. Just a few months after fitting his camera, he spotted
:10:48. > :10:54.a motorist driving dangerously. As he followed, the driver began to
:10:54. > :11:04.speed up. What happened next is distressing. Within moments the
:11:04. > :11:04.
:11:04. > :11:09.camera captured a shocking hit and run. There was a 75-year-old man...
:11:09. > :11:14.She'd just knocked him over, a completely insane manoeuvre. You
:11:14. > :11:18.would never do that if you were a rational, sensible person.
:11:18. > :11:28.After making sure the man was getting help, he caught up with the
:11:28. > :11:29.
:11:29. > :11:35.driver. You do not realise, you have just run over a person. Shocking
:11:35. > :11:39.behaviour. It is absolutely terrible. Luckily the pedestrian
:11:39. > :11:44.suffered only minor injuries. The footage was given to the place and
:11:44. > :11:47.the driver was convicted of dangerous driving and given a 12
:11:47. > :11:52.month suspended prison sentence. So this camera was vital in all of
:11:52. > :11:57.this. Absolutely, if the evidence had not been on camera, she would
:11:58. > :12:01.have got away with that. These cameras are widely used in Russia
:12:01. > :12:11.where they even captured footage of the meatier that hurtled to Earth in
:12:11. > :12:31.
:12:31. > :12:34.February. Drivers have posted hours closer to home in fake accidents.
:12:34. > :12:39.These so-called cash for a crash collisions are caused by criminals
:12:39. > :12:44.looking to make money from an insurance claim. They cost the
:12:44. > :12:49.insurance industry nearly �400 million last year. They can help
:12:49. > :12:54.identify what are the genuine claims and that can mean savings for the
:12:54. > :13:04.customer and a smoother claims process and it is a for everybody.
:13:04. > :13:04.
:13:04. > :13:07.This road haulage firm in Somerset had cameras fitted in all of its 65
:13:07. > :13:12.trucks. The main reason we have done it is to protect ourselves from
:13:12. > :13:17.spurious claims. Drivers are a little bit apprehensive, and some of
:13:17. > :13:20.them saw it as a spy in the cab and maybe we could listen in to what
:13:20. > :13:26.they were saying. But now they realise they are there to protect
:13:26. > :13:32.them and they can be a beneficial tool. And it has also helped the
:13:32. > :13:39.insurance premium. Our policy has been reduced by 10%. That is over
:13:39. > :13:43.�10,000 in savings straightaway this year. So would this appealed to the
:13:43. > :13:49.rest of us? It is definitely investigating if it is going to work
:13:49. > :13:58.for you. If you could save 10% or 15% on your premium, it could pay
:13:58. > :14:01.off in years to come. With these cameras becoming more common on the
:14:01. > :14:11.roads of Britain, drivers beware, because you never know who might be
:14:11. > :14:13.
:14:13. > :14:16.watching. That was terrifying! That Big
:14:16. > :14:22.Brother argument is interesting, but when you see what a difference it
:14:22. > :14:26.can make, it makes you think. does. There are, one feels, too many
:14:26. > :14:31.cameras watching us all the time. You can't even be Dame Helen mirror
:14:31. > :14:35.and without someone filming you all the time. But when you look at that,
:14:35. > :14:39.and you see someone being knocked over like that and then the girl
:14:39. > :14:43.completely denying it, it does make you think it is not a bad idea.
:14:43. > :14:51.Caroline is one of the growing band of famous faces who go off around
:14:51. > :14:54.the country to infuse about famous -- about popular places.
:14:54. > :14:58.however, send our hairdresser, Michael Douglas around. People will
:14:58. > :15:03.tell a man with a pair of scissors anything he asks!
:15:03. > :15:11.I am in the beautiful city of Edinburgh for my latest assignment.
:15:11. > :15:17.This has to be one of the hottest tickets I've had today. I'm at
:15:17. > :15:24.Edinburgh's other festival, a pageant of colour, drums, dance and
:15:24. > :15:31.flames, welcoming the start of summer. This is Angus and he founded
:15:31. > :15:36.the Fire Festival. 26 years ago to the day. I've grown up here in
:15:36. > :15:43.Scotland, and found out that the big hill behind us, Arthur's seat, from
:15:43. > :15:49.medieval times had been the home of this amazing Fire Festival called
:15:49. > :15:56.Beltane. It means sacred fire, from gay lick, and the coming of summer
:15:56. > :16:03.was thought to be the most important day. When we started it, it hadn't
:16:03. > :16:10.happened so 96 years. We started something that was more than 1000
:16:10. > :16:19.-year-old tradition. What is the black mark? It is a smudge from wood
:16:19. > :16:24.that was burnt in the fire last year. Take a look.That taken at
:16:24. > :16:29.least six months off me! I've noticed a few of them have bald
:16:29. > :16:32.patches. Have you noticed that? Why'd you think that is? This is
:16:32. > :16:40.Richard, one of the photographers who will capture the spectacle
:16:40. > :16:50.tonight. When did you last go to the salon for a haircut? I think it was
:16:50. > :16:51.
:16:51. > :16:57.about 1986. So, what ever I feel is appropriate? Yes. I will be painted
:16:57. > :17:02.up so I don't feel like an official photographer. At the festival, we
:17:03. > :17:08.have a group called the remnants of winter. They confronted the May
:17:08. > :17:16.Queen, but they can't stop her coming through. You look completely
:17:16. > :17:26.different. I can't quite believe it! Take a look. Yeah, nice and short
:17:26. > :17:32.
:17:32. > :17:36.here. You get the extremes of people who are really into this, and then
:17:36. > :17:46.people who are here in a kind voyeristic mode. Where have you come
:17:46. > :17:47.
:17:47. > :17:54.from? Florence, Italy. Just for this? Just for this.Can you talk me
:17:54. > :18:04.through your outfits? It's supposed to be a crescent moon. It's got gel
:18:04. > :18:14.on it! Is it not flammable?No, the gel is water-based. What do I know
:18:14. > :18:19.
:18:19. > :18:24.about gel? So, you met here. Are you still in love? We are engaged!So,
:18:24. > :18:31.this is the lovely Robin. In the spirit of this evening, we are going
:18:31. > :18:37.to give you a sort of pagan triangle hairdo. I have just come to this
:18:37. > :18:44.place. I would recommend anyone to come again. It is very friendly.
:18:44. > :18:48.Probably more naked people by the end of the night! Naked people?I'm
:18:48. > :18:52.told that's what people actually come here for, the naked people.
:18:52. > :19:02.have done a little fish tail plat through here, with a bit of height
:19:02. > :19:04.
:19:04. > :19:11.on top. Take a look! I love it! Thank you very much. It's a
:19:11. > :19:14.pleasure. That's it. Only one thing left to do. Toast!
:19:14. > :19:18.If you are going to take your clothes off in Edinburgh, you might
:19:18. > :19:28.as well do it by a bonfire. Especially with the spring we've
:19:28. > :19:28.
:19:28. > :19:34.just had! You didn't do that, Caroline, for your new documentary?
:19:34. > :19:38.Strip off? I did a couple of things that I wasn't entirely keen on. I
:19:38. > :19:46.went up a tree with a tree surgeon. I'm not mad keen on heights. I bet
:19:46. > :19:53.you love all that, don't you? don't mind heights. I tried to be
:19:53. > :20:03.brave, but I was really shaky and my mile -- my mouth was really dry. I
:20:03. > :20:04.
:20:04. > :20:09.did a sort of gazelle leap. You jump through the trees. I did all right.
:20:09. > :20:19.You had a bit of a go of the toss of the caber as well, didn't you?
:20:19. > :20:26.Please do let go of it! I don't like it! I really don't like it! I could
:20:26. > :20:32.kill people! I could kill you! Please don't do it. Its at salute
:20:32. > :20:40.the terrifying. I'm going to try and lift this. -- it is absolutely
:20:40. > :20:48.terrifying. If I had a sports bra on, I would have that up by now! I
:20:48. > :20:53.didn't like it! You can tell. It was really terrifying. You can't get any
:20:53. > :20:58.sense of what that is really like, but it seems to go on forever. Of
:20:58. > :21:05.course, the balance is so... It has no balance and it is massively
:21:05. > :21:09.heavy. You can't lift it. I don't know how heavy they are, but it's
:21:09. > :21:17.ludicrously heavy. Steve and there is world champion caber toss, and
:21:17. > :21:20.they make it look easy. But it's virtually impossible. This is part
:21:20. > :21:26.of your new series where you look at National Parks throughout the
:21:26. > :21:28.country. You've got three. You've got Loch Lomond, Snowdonia and the
:21:28. > :21:37.new Forest. How do the Parks compare? What were the main
:21:37. > :21:43.differences? It's extraordinary. For me, it's not just the location, but
:21:43. > :21:48.the countryside, the people, the food, the music... We are so
:21:48. > :21:53.diverse. These islands are so diverse, and it's thrilling. I was
:21:53. > :21:58.literally a week somewhere, Scotland, and then the next week I
:21:58. > :22:06.was in the new Forest. The next minute I'm on you to fall hills and
:22:06. > :22:12.then I am in dry heathland. And how can it be so different? How can
:22:12. > :22:17.everything sound so different. The accents are different, and the food.
:22:17. > :22:24.It's really exciting. How can you compare documentaries with all the
:22:24. > :22:31.drama? As long as I'm showing off, I just don't care! I like all of it.
:22:31. > :22:40.It's nice to have... I'm doing a play next. Isn't Rory Bremner in it?
:22:40. > :22:43.Yes, and Patricia Hodge. As long as I can do a bit of everything.
:22:43. > :22:50.can see Caroline in her National Parks. It begins tomorrow night on
:22:50. > :22:56.ITV. As we have seen many times, our wildlife man, Mike Dilger, can sit
:22:56. > :23:00.for hours on end is to see spectacular displays of nature.
:23:00. > :23:06.There are some sites that even Mike's ironclad can't wait for, so
:23:06. > :23:08.he found a way of speeding things up a bit.
:23:09. > :23:14.The brilliant yellow of the lesser celandines heralds the arrival of
:23:14. > :23:19.spring. You can find them in Woodlands, graveyards or on sunny
:23:19. > :23:23.banks. These tiny wildflowers close up at night to protect their pollen
:23:24. > :23:29.and nectar. As the temperature rises in the morning, the petals slowly
:23:29. > :23:36.unfurl, and a flower opens. This is a process you wouldn't normally CMS
:23:36. > :23:42.you were staring at the flowers for hours on end. Tim Shepherd is an
:23:42. > :23:48.award-winning wildlife cameraman. For the last 25 years, he has been
:23:48. > :23:52.specialising in the complicated craft of timelapse. You will have to
:23:52. > :23:56.explain to the uninitiated. It is speeding up time by running the
:23:56. > :24:02.camera more slowly than you normally would, and then playing it back the
:24:02. > :24:07.same speed as you normally would. You can make a day into a second, an
:24:07. > :24:12.hour into a second. Tim's work is to see the beauty of nature are
:24:12. > :24:16.unfolding, and capture sites that would normally be too slow to be
:24:16. > :24:22.seen. Give him a carpet of celandines opening in all their
:24:22. > :24:26.glory, and he's really in his element. Celandines are woodland
:24:26. > :24:36.edge species. They are common, but in places like these, where there is
:24:36. > :24:36.
:24:36. > :24:39.a bit less disturbance, some trees and some shade, they do really well.
:24:39. > :24:46.Tim's tripod runs along on skateboard wheels. For this shot,
:24:46. > :24:50.the rig will move just two centimetres between photos, taking a
:24:50. > :24:58.picture every ten seconds, so there shouldn't be any jolts or jumps in
:24:58. > :25:02.the action when it is played back. It will take a while to get from one
:25:02. > :25:07.end of the ladder to the other. camera should track along the
:25:07. > :25:12.flowers, with them opening as it comes to a halt. For a perfect
:25:12. > :25:18.timelapse, we would have a windless day and a cloudless sky. We've got
:25:18. > :25:24.neither, so fingers crossed. On a day like today, the sun is going in
:25:24. > :25:29.and out all the time, which affects the exposure and gives a flickering
:25:29. > :25:36.effect on the final shot. It makes the shot looks spectacular. We won't
:25:36. > :25:40.know for certain until the shot finishes. The celandines are merging
:25:40. > :25:46.much later this year because it's been such a cold spring, and they
:25:46. > :25:51.are still out far earlier than most of our woodland flowers. This means
:25:51. > :25:54.they supply a vital nectar source for all manner of emerging insects.
:25:54. > :25:59.This honey bee and a small tortoiseshell butterfly are the
:25:59. > :26:05.first I've seen this year. After two hours, the lesser celandines are
:26:05. > :26:13.finally fully open. Time to check the camera. I sequenced it all on
:26:13. > :26:18.the computer, so here we go. There is a bit of wind movement, and as
:26:18. > :26:26.Tim predicted, the sun coming in and out has caused some flickering.
:26:26. > :26:32.happens is, the sun comes out, and you get a bit of a pain. There! They
:26:32. > :26:37.only opened once, and that's it. It is your only chance a day to get a
:26:37. > :26:47.little sequence. You need to do it several times. And when he does, he
:26:47. > :27:11.
:27:11. > :27:16.favourite flowers, and today, I know kind and took a picture of her lying
:27:16. > :27:25.in her celandines over the weekend. My husband took that. It's a
:27:25. > :27:31.gorgeous picture. There are six dogs around my feet. You can't see them.
:27:31. > :27:34.I said feet because it is a family show! Miranda, you've been looking
:27:34. > :27:40.at some more timelapse is for us. Time lapses have revealed some
:27:40. > :27:45.amazing things in the animal world, and this is an amazing one. This is
:27:45. > :27:51.filmed in Malaysia. Somebody's cat had filmed in a dead gecko -- had
:27:51. > :27:59.brought in a dead gecko. They had a bit of problem with ants, and the
:27:59. > :28:05.ants are coming in and literally stripping the gecko. That's like a
:28:05. > :28:10.Tim Burton film! They are taking away the bones, even. It shows what
:28:10. > :28:13.effective scavengers they are. you know how quick that was?
:28:13. > :28:20.Interesting that the head went one way and the body the other.
:28:20. > :28:24.other one you've got... This is one of my all-time favourites. This was
:28:24. > :28:29.filmed in the Sahara, one of the David Attenborough films. They've
:28:29. > :28:33.condensed a years worth of movement into just 14 seconds. You can see by
:28:33. > :28:38.the background that it really is the sound that's moving. I remember
:28:38. > :28:48.learning about this in geography at school, and sand movement not making
:28:48. > :28:51.
:28:51. > :29:01.any sense. But this footage really make sense of it. We don't do much
:29:01. > :29:05.tweeting on the show. I don't tweet. On Radio 4 we are basically
:29:05. > :29:10.showcasing British birdsong and every day before the news you can
:29:10. > :29:15.hear a different type of British birdsong. You get a little
:29:15. > :29:20.description and a caricature of the bird, followed by its song.
:29:20. > :29:25.Caroline, we understand you were a bird watcher. I was a member of the
:29:25. > :29:31.young ornithologists club. I tend to do it more from the kitchen now when
:29:31. > :29:35.I am cooking, but I still love them. It is a lovely thing to do for
:29:35. > :29:39.children. If you have children at home who need to be told Martha's is
:29:39. > :29:45.a good part of the world because you need to get them around the
:29:45. > :29:53.television now. Marty Jopson demonstrates how equations and a
:29:53. > :29:58.slide rule devastated Hitler's greatest weapon. In 1944, and Nazi
:29:58. > :30:04.inventors launched the feed two. It was the stuff of science fiction, a
:30:04. > :30:12.supersonic rocket of mass destruction that hurtled through the
:30:12. > :30:16.air at four times the speed of sound. The unstoppable missiles
:30:16. > :30:20.carried one-time warheads and could be fired from mobile launchpad is
:30:20. > :30:26.way behind enemy lines. Five minutes later they brought death and
:30:26. > :30:32.destruction on London. Unlike the doodlebug which could be shot out of
:30:32. > :30:37.the sky, this flew 50 miles up in the air, above the atmosphere, where
:30:37. > :30:45.conventional weapons could not touch it. But it did have a weakness and
:30:45. > :30:50.that was to do with mathematics. During the war Eileen served in
:30:50. > :30:56.fighter command 's filtered room where aircraft and missiles were
:30:56. > :31:03.tracked by radar. That is me.How long ago was this? This is 70 years
:31:03. > :31:08.ago? That is right.Tell me when you thought something strange was coming
:31:08. > :31:17.in. We had been warned there was going to be another vengeance
:31:17. > :31:22.weapon, codeword Big Ben and the first officer to hear this must get
:31:22. > :31:28.on a chair and yell it out three times. And guess what? It was me and
:31:28. > :31:35.it was that terrible time when the very first V2 landed on Chiswick and
:31:35. > :31:41.it killed a top people and generated a fear. Hitler had developed
:31:41. > :31:46.something terrifying. After D-Day the Germans trained them on Antwerp,
:31:46. > :31:51.killing more than 800 people. The only way of stopping them was by
:31:51. > :31:56.destroying their mobile launchpad. Using little more than a slide rule,
:31:56. > :32:02.Eileen had to track them down. Because a rocket was a projectile,
:32:02. > :32:11.it went on a predictable path. We knew a rocket would go in the form
:32:11. > :32:17.of a parabola. It accelerates up and then gravity takes over and pulled
:32:17. > :32:23.it back down. Once the rocket was launched, it stayed to that certain
:32:23. > :32:29.path. It is a mathematically defined curve and it is symmetrical as well
:32:29. > :32:37.and allows you to do the maths. that we could work out the launch
:32:37. > :32:47.site. Eileen, let's see a parabola in action. We have got a model
:32:47. > :32:53.
:32:53. > :32:57.rocket. Three, two, one. Fantastic. Gosh, that is high. In fact, so high
:32:57. > :33:03.that most of the parabola was hidden in the clouds, so you will have to
:33:03. > :33:09.take my word for it. This is our rocket. It has landed in the ground.
:33:09. > :33:13.How did you work out where you were taking off from? We needed another
:33:13. > :33:18.piece of information which we got from the radar stations and it would
:33:18. > :33:22.be someone on the parabola and with those two bits of information we
:33:22. > :33:26.could extrapolate that curve right the way back. You have got a point
:33:26. > :33:32.up here and you have got a point to stand there and you join them
:33:32. > :33:40.together with a curve. Processing the rocket's height and speed on a
:33:40. > :33:45.parabolic trajectory, Eileen made some complicated calculations.
:33:45. > :33:50.went straight up to start with before it entered into the curb. All
:33:50. > :33:57.this was taken into consideration. We would calculate the position
:33:57. > :34:00.right over there of the launch site. Eileen had just six minutes to
:34:00. > :34:05.make her calculations. Any longer and the mobile launchers would
:34:05. > :34:08.escape before they could be bombed. It was a ferocious calculation you
:34:08. > :34:10.had to do and they could be bombed. It was a ferocious calculation you
:34:11. > :34:17.had to do at this blight -- slide rule. You must have felt the
:34:17. > :34:25.responsibility. It was a terrific killing people and finally by the
:34:25. > :34:30.end of March we despite killing thousands of people the missile
:34:30. > :34:36.failed to change the course of the war. Mathematics helped beat the
:34:36. > :34:41.world's most sophisticated weapon. We hope you are having a lovely bank
:34:41. > :34:47.holiday, Eileen. You did not have a successful mammoth job. Marcus has
:34:47. > :34:51.always been a big weakness and I stopped learning it at 13. I once
:34:51. > :34:56.worked for a security firm and I got a job as a temp and they said they
:34:56. > :35:02.were going to put me in a room with an adding machine and it had a roll
:35:02. > :35:07.of paper and I was up to their in paper and I had not done any maths.
:35:07. > :35:10.They said, you are delightful, but you must go now. Earlier on we
:35:11. > :35:16.showed you the line-up for the biggest sporting event at the
:35:16. > :35:24.weekend, the Mascot Grand National from Kempton Park. Our mascot,
:35:24. > :35:30.Onesie, was involved for the first time. He was a late entry. We have
:35:30. > :35:36.no idea who one. We have had a sweepstake in the office and I got
:35:36. > :35:44.Lily the panda. I unbelievably got Onesie. Someone has drawn this for
:35:44. > :35:54.me. I have got the swift. Let's see how we all got on and how Onesie
:35:54. > :35:54.
:35:54. > :36:40.Apology for the loss of subtitles for 46 seconds
:36:40. > :36:49.second this year. He was fourth. Come on in, Onesie. Shake hands with
:36:49. > :36:59.the builder. Have you ever seen such a determined squirrel? Sit yourself
:36:59. > :37:00.
:37:00. > :37:05.down quickly and reveal yourself. Who could it be? Well done. It was
:37:05. > :37:11.so hot, but I loved it. competitive were you, going down on
:37:11. > :37:19.the outside. A few of them were wearing trainers and I started right
:37:19. > :37:27.at the back. It was brilliant, I loved it. Very quickly, your bank
:37:27. > :37:32.holiday apologies. Tom says, sorry for soaking you with water, dad.
:37:32. > :37:36.Louise would like to apologise to her boyfriend Lee for the rant she
:37:36. > :37:42.had because of him not putting the pees in the steamer. She says she
:37:42. > :37:50.loves you very much. Hardly the dog would like to apologise for doing
